Lewis dot structure for NH3 is depicted by the outer electrons surrounding the N atom.
The Lewis dot structure in the case of NH3 reveals that the N atom joins one pair of e- with
each of the three hydrogen atoms, resulting in a total of 3 joined pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like form because of the distribution of the outer electrons according to its Lewis dot structure.
In the dot symbol depiction of NH3, the nitrogen atom is enveloped by three dots, each representing a pair of joined electrons with a hydrogen atom.
